A threshold-based model for detecting PHY preamble.
This model assumes that a preamble is successfully detected if SNR is at or above a given threshold (set to 4 dB by default). However, if RSSI is below a minimum RSSI (set to -82 dBm by default), the PHY preamble is not detected.

A pure virtual method that must be implemented in the subclass.
This method returns whether the preamble detection was successful.
| rssi | the RSSI of the received signal. |
| snr | the SNR of the received signal in linear scale. |
| channelWidth | the channel width of the received signal. |
Implements ns3::PreambleDetectionModel.
